Definitions

  • the present invention relates to methods for laser welding of elements of sintered material.
  • JP-A-08 290292 discloses a method for laser welding of a first element and a second element, in which at least said first element is of sintered material, and in which a laser beam is focused in proximity to the welding area, said method being characterised in that the laser welding operation is conducted with the addition of weld material, in form of a solid insert.
  • the invention relates to a method for laser welding of a first element and a second element, in which at least said first element is of sintered material, and in which a laser beam is focused in proximity to the welding area, wherein the laser welding operation is conducted with the addition of weld material, characterised in that the weld material is adducted simultaneously to the welding operation and is in form of metal dusts.
  • the dust used as weld material is preferably a mixture of metal dusts, whose composition varies according to the sintered material to be welded.
  • the grain size of the dusts preferably ranges between 0.010 and 0.100 mm.
  • the dusts are adducted to the weld area by means of an adduction nozzle.
  • Said nozzle can be a separate nozzle from the nozzle normally used for the adduction of the covering gas necessary during the laser welding operation.
  • a single nozzle can be used both for the weld dusts and for the covering gas. The choice depends mainly on the geometry of the junction to be welded.
  • a nozzle N adjacent to the laser focusing head is provided a nozzle N for the adduction of the covering gas normally used during laser weld processes.
  • FIG. 3 A second possible implementation of the invention is shown in Figure 3, with a representation similar to the one of Figure 1; in said figure, the same reference number of the previous figures are used to designate elements that are technically equivalent to those already described above.
  • a throat with defined geometry designated by the reference number 6, is provided, preferably formed in part in the component 1 and in part in the component 2.

  6. Procédé selon la revendication 1, caractérisé en ce que l'angle d'addition des poussières s'étend entre 15° et 45° relativement au plan de la zone de soudage (W).
  7. Procédé selon la revendication 1, caractérisé en ce que le soudage au laser est réalisé à des zones de jonction entre le premier et le second éléments (1, 2) et à ladite jonction entre le premier et le second éléments (1, 2) est ménagé un siège ou une gorge pour recevoir le matériau de poussière.
  8. Procédé selon la revendication 7, caractérisé en ce que le siège ou la gorge est formé en partie dans le premier élément (1) et en partie dans le second élément (2) à souder.
  9. Procédé selon la revendication 1, caractérisé en ce que la position relative de l'axe du faisceau laser (L) relativement au plan de la zone de soudage (W) est choisi selon les matériaux constituant ledit premier et second éléments (1, 2).
  10. Procédé selon la revendication 1, caractérisé en ce que le faisceau laser (L) est focalisé dans une plus grande mesure sur l'un desdits premier et second éléments (1, 2) que sur l'autre.
  11. Procédé selon la revendication 1, caractérisé en ce que le faisceau laser est façonné avec une section non-circulaire, comme une section carrée ou rectangulaire.
  12. Procédé selon la revendication 1, caractérisé en ce que le faisceau laser est façonné au moyen d'un système optique double foyer avec variation de la distance entre les points de laser produits.
